HazMat Fee

An item is classified as a dangerous good if our website displays Hazardous Material (HazMat) information for it. There is a HazMat shipping fee for each item that qualifies as a dangerous good, except in the following scenarios:

The shipment is processed through FedEx Ground under the Limited Quantity option.

Each bottle is packed as an Excepted Quantity, with a maximum of 1g for items in class 6.1 packing group I or II, and up to 25g for all other hazardous materials.

If shipping is charged to your FedEx account, the HazMat fee will be billed directly by the courier. Otherwise, the fee will be included on your invoice. To help you avoid the HazMat fee, we can package a 5g order of a class 6.1 packing group I or II material as five separate 1g units, and a 100g order of any other dangerous good as four 25g units. This packaging adjustment will be made unless you instruct otherwise on your purchase order. Below, you will find the fee schedule from FedEx for handling hazardous materials.

Description

3-Bromo-4-iodopyridine is a heteroaromatic dihalogenated pyridine featuring complementary halogen handles for cross-coupling reactions. The bromine and iodine substituents enable sequential functionalization via palladium-catalyzed processes, offering strategic control in synthetic sequence design. This electron-deficient scaffold integrates efficiently into complex molecular architectures under standard conditions.

Application

3-Bromo-4-iodopyridine serves as a versatile building block in cross-coupling chemistry, enabling efficient construction of substituted pyridine scaffolds. The complementary halogenation pattern facilitates sequential Pd-catalyzed coupling reactions, with bromide typically reacting first under standard conditions. Its bench-stable nature and predictable reactivity support reliable functionalization in medicinal chemistry and materials synthesis workflows.
